\"5%5E%28x-1%29=3%5Ex\" Start with the given equation.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"log%2810%2C%285%5E%28x-1%29%29%29=log%2810%2C%283%5Ex%29%29\" Take the log of both sides\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28x-1%29log%2810%2C%285%29%29=x%2Alog%2810%2C%283%29%29\" Pull down the exponents\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%2Alog%2810%2C%285%29%29-log%2810%2C%285%29%29=x%2Alog%2810%2C%283%29%29\" Distribute\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-log%2810%2C%285%29%29=x%2Alog%2810%2C%283%29%29-x%2Alog%2810%2C%285%29%29\" Subtract \"x%2Alog%2810%2C%285%29%29\" from both sides.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-log%2810%2C%285%29%29=x%28log%2810%2C%283%29%29-log%2810%2C%285%29%29%29\" Factor out the GCF \"x\" on the right side\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-log%2810%2C%285%29%29=x%2Alog%2810%2C%283%2F5%29%29\" Combine the logs on the right side using the identity \"log%28b%2C%28A%29%29-log%28b%2C%28B%29%29=log%28b%2C%28A%2FB%29%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-log%2810%2C%285%29%29%2Flog%2810%2C%283%2F5%29%29=x\" Divide both sides by \"log%2810%2C%283%2F5%29%29\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3.15066=x\" Evaluate the right side (using a calculator). Note: the value of \"x\" is now approximate\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x=3.15066\" Rearrange the equation\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the solution is approximately \"x=3.15066\"
